  • Patent number: 10203041
    Abstract: Described are valve stems for wheels or other pressure vessels that may be installed from the exterior of a wheel or pressure vessel without access to the interior, pressure retaining areas. The valve stem may include a body with a barrel and taper. A neck may be between the body and a base that includes a flange, a flange landing, and an air aperture. An air channel runs vertically through the valve stem to allow air to pass from one side of the valve stem to another with a valve core or other flow control device. The base of the valve stem may include a groove that allows the valve stem to be installed into a hole by twisting such that the groove may ride along the rim of the hole and guide the valve stem into a fully seated and sealed position.

  • Publication number: 20140034203
    Abstract: This invention describes a system to maintain equal pressure in a pair of dual tires, and also incorporates a valve mechanism that will prevent one dual wheel tire from going flat in the event the other dual wheel tire experiences a rapid air loss. Dual wheels are typically mounted on the vehicle hub with both wheel disc faces in direct contact with each other. To ensure equal pressure in both tires, this invention has air passageways machined into the wheels such that the air passageways meet at the interface between the wheels where the wheel disc faces are in direct contact. These junctions are sealed by a rubber seal or gasket. Both tires can then be inflated or deflated simultaneously through a standard air valve located on either wheel. Where a dual wheel arrangement requires the use of an intermediate piece between the dual wheels, air passageways can connect the two-piece wheels via intermediate air passageways going through the common intermediate piece.

  • Patent number: 8122926
    Abstract: This CTI Valve manifold of this invention creates a wheel-manifold-CTI Valve combination such that an air passageway coming from the wheel hub through the manifold brings air to the valve, and an airway from the valve through the manifold provides air to the tire cavity, preferably via an air passageway in the wheel. The manifold also allows for the CTI valve to deflate the tire, a typical operational requirement for central tire inflation systems.

  • Patent number: 8047247
    Abstract: The invention relates to a tire valve (10) comprising a valve body (11) which penetrates a bore (21) of a rim (20), particularly a vehicle rim, embodies a bottom valve body section (13) that is disposed on one side (23) of the rim (20), particularly in the interior of the rim, in the mounted state as well as a top valve body section (15) that protrudes from the rim bore (21), and is configured so as to cooperate with a cap nut (17) in the area of the top valve body section (15). The bottom valve body section (13) forms a stop collar (19) which is used as an abutment for a flat peripheral section (27) of the rim bore (21) and widens the bottom valve body section (13) relative to the top valve body section (15) beyond an internal width of the rim bore (21). The peripheral section (27) of the rim bore (21) can be braced against said stop collar (19) by tightening the cap nut (17).

  • Publication number: 20110175716
    Abstract: The present invention is a valve for use in a central tire inflation system including a casing securable to the rim of a vehicle in communication with the tire that houses a main body connectable to a pressurized fluid supply of the central tire inflation system, and a valve member moveable within the main body to control the flow of air through the valve. The valve can be mounted flush on the exterior surface of the rim or in a recessed position within the rim, and can be connected to a manifold that is able to control the flow of pressurized fluid from the central tire inflation system to each valve and tire connected to the valve. The operation of the manifold and pressurized fluid supply can be controlled utilizing a controller operably connected to the manifold and fluid supply, and to sensing devices that supply information regarding the operational conditions of the vehicle to the controller to assist in adjusting the inflation of the tires as necessary.

  • Publication number: 20110057503
    Abstract: The instant invention is a pressure release safety system for a multi-piece wheel rim and tubeless tire combination, teaching designs for automatically relieving/releasing pressure as part of its disassembly. In this invention, fastening elements used to hold together portions of a wheel rim are provided with a blocking device or devices that prevents loosening and/or removal of fastening elements until said blocking device is first moved from a blocking position, where movement of the blocking device from its blocking position directly or indirectly opens or requires the opening of a pressure relief channel or channels—allowing, enabling and effecting depressurization of the sealed pressure vessel. When applied in the context of a tubeless two-piece wheel/tire assembly, the invention advantageously may include a blocking or safety device (typically in the form of a ring) that covers all or a critical portion of the nuts/studs that hold the two piece wheel together.

  • Publication number: 20110056602
    Abstract: A rigid air valve comprises a valve body and a valve stem. The valve body has a shoulder for abutting an inner cylindrical surface of the wheel. A first protruding portion extends radially outwardly from the shoulder into a valve hole. The first protruding portion extends to a tire-side surface of the wheel. A second protruding portion extends both radially inwardly and axially outwardly through a hole in a center plate of the wheel to thereby define a curved air passageway extending from a first opening in the first protruding portion to a second opening in the second protruding portion. The valve stem has external threads for engaging complementary internal threads inside the second protruding portion. The valve stem includes a valve for selectively admitting air into a tire when mounted on the wheel. This valve is robust and durable, reduces inflation time and eliminates leaky spuds and O-rings.
